SEPARABLE FASTENER.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed May 23,1905- Serial No. 261.772.

To (ZZZ whom, if? Duty concern:

Be it known that I, HENRY R. BAKER, a citizen of the United States,residing at North Attleboro, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inSeparable Fasteners, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to separable fasteners particularly adapted forconcealed use, and has for its objects strength, cheapness, andsimplicity.

The invention consists in the novel construction and combination ofparts hereinafter described, and illustrated in the accompanyingdrawings, wherein- Figure 1 is a top plan view of a bracelet equippedwith my novel fastener; Figs. 2 and 3, top and side elevations,respectively, of the lever-tube; Figs. 4 and 5, similar elevations,respectively, of the latch and its block; Figs. 6, 7, and 8,longitudinal sections on linear in of Fig. 1, showing the partsrespectively in engaged, partially engaged, and disengaged positions;and Fig. 9, adetail view of thelever. I Like reference charactersindicate like parts throughout the views.

In the drawings, A and B represent the tubular wings of an ordinaryconcealed-joint bracelet, provided at their adjacent extremities withsemicircular cuttings to form a circular opening 0 in the top of theclosed bracelet. In the end of the wing A and projecting beyond the sameis fixed, by solder or frictionally, a curved tube a, elliptical incrosssection and having anend wall (0, provided with a' rectangularopening a A circular perforation o in the upper portion of the tuberegisters with the opening 0 in the wings. Upon a pin a traversing thetube a and fixed in its walls, is a lever c with a pointed freeextremity c and a shoulder 0 upon its lower portionadjacent its fulcrum.A projection 0 upon the upper margin of the lever traverses the openings(4 and 0 and has the usual nailchannel 0* in its upper surface. In theadjacent end of the other wing B is soldered or otherwise secured thebase d of a spring-arm (5, provided upon its extremity with a barbed Thebase (Z has a perforahead or hook (Z tion (Z3 to loosely admit the bentor hooked end c of a flat bar 6, which has upon its outer end anelliptical flange, wall, or lug c with an oblong opening a to permit thepassage and free vertical vibration of the spring-arm cZ. By virtue ofthe loose engagement of the hooked end 0 with the base CZ the Wall ispivotally connected with the spring-arm. When the spring-arm. andadjacent parts are assembled, the wall 0 is some distance within the endof the wing B.

When thewings A B are in engaged position, the wing B overlaps the tubea and the extremity of the lever 0 is retained in elevated position bythe head of the arm d. The head d engages the inner face of the wall a,as shown in Fig. 6. To disengage the parts, the projection c isdepressed, thereby forcing the head of the arm d out of engagement withthe wall a, as illustrated in Fig. 7. The parts when disengaged are asshown in Fig. 8, wherein the point 0 is retained in elevation above theplane of the opening a by virtue of the shoulder 0 The head (Z isretained against excessive elevation by the wall 6 Having described myinvention, what I claim is 1.' A separable fastener of the classdescribed comprising two engaging portions, one member comprising atube, a wall upon the end of the tube provided with an opening, a leverpivotally mounted in the tube, a spring-arm fixedly mounted in the otherportion, a wall pivotally connected with the spring-arm and providedwith an opening through which the spring-arm passes, and a hook upon thefree extremity of the spring-arm adapted to engage the inner surface ofthe tube-wall.

2. In a bracelet, a catch for its wings, the same comprising a leverpivotally mounted within the hollow end of one of the wings, and aspring-arm provided with a barbed head secured at one end within thehollow end of the other Wing, the adjacent ends being provided withopenings for the movement of the springarm, the said spring-arm tendingto retain its head in engagement with the end of the ad ja-.

cent wing.

In a bracelet, a catch for its wings, the same comprisinga leverprovided with a pointed free extremity pivotally mounted in one Wing, atsupporting-shoulder upon the lever, In testimony whereof I have affixedmy siga projection upon the upper margin of the nature in presence oftwo Witnesses. lever, Walls with openings in the ad acent HENRY R.BAKER. wlngs, a spring-arm 1n the second Wing provided With a barbedhead traversing the open- \Nitnesses:
